Cast Diagram Radians. In the first quadrant the values are all positive. The sine wave below has been divided into 4 quadrants.
The cast diagrams for the tangent function are simpler in form than the others you merely add multiples of 180 to obtain all the solutions needed. It saves having to use trigonometric graph. Find the two angles θ between 0 and 2π radians for which tan θ 3 8.
Because we want answers between 0 and 2π we correct θ pv by adding 2π to get 4 97 and state.
From the above diagram the sine wave is. It saves having to use trigonometric graph. The cast diagrams for the tangent function are simpler in form than the others you merely add multiples of 180 to obtain all the solutions needed. The calculator or algebra coach gives θ pv arctan 3 8 1 313 radians.
